Tube Preamp with Solid State Amp?

Preamp tubes all 6H30P-DR and NOS Tungsoll 6550 black plate

I've been using a 1981 Conrad Johnson PV2ar tube preamp with a 100W modified Hafler SS amp to drive a pair of Klipschorns and have been entirely satisfied with the sound.
Originally a CJ MV75 tube amp was part of my system but the heat generation, tube costs, and recurring power switch failures (!!) convinced me that maintenance on one tube device was enough. 
Perhaps there are sonic nuances lost by going solid state for the amp....but my system sounds so good the way it is I'll never go back.
If possible, audition multiple amps in your system and pick the one that sounds best to you.

By the way, my Schiit Freya/Had "Firebottle" SEP amp combo cost less than 2 grand (the Had amp was used for a few months), and is an astonishingly coherent and musical system that for my tastes provides what SS gear, try as they may, does not. 2 REL subs for low bass shy Heresy IIIs make it thunder, although I'm tied to efficient speakers (in a good way).

I’m adding an AR tube pre to my system tomorrow. Very interested to see how it sounds. 

Vinnie Rossi LIO with DHT preamp/dac section into internal Mosfet power amplifier. No transformers, No interconnects, power supply isolated from line voltage with Ultra Capacitor bank. External low noise regulated power supply for tube filaments. Runs all manner of DHT tubes - 300b, 2a3, 45's, PX25, PX4 etc... etc. Awesomeness.
